It seems to me that the benefit of the Pro-series scanners is that you don't
have to charge the batteries in the scanner. I just pop out one set and
drop the other set in. I can charge the batteries (NiMH or NiCad) in a
quality charger that uses pulse charging and overcharge protection in a lot
shorter time than it takes to charge them in the scanner. And I'm free to
take the scanner anywhere I want while the other batteries are charging, I'm
not tied to a power source for the 14+ hours it takes to charge the
batteries in the scanner. Until such time as Uniden finally gets a clue and
drops their proprietary battery packs in favor of a standard AA battery
holder, I'll keep buying RS/GRE handheld scanners.

i have two
a pro-39 & another one.
both have been used with nimh for 2 years now.
i'm still getting about double the time span per charge compared with
nicads.

agree though, it depends on the charging circuit, but i've always found
true
constant current chargers don't seem to mind & give a good level of
charge.

it will take a bit longer, but no problems.
(dif capacity) in simple terms without
going into too much tech stuff in almost
all applications, they can directly replace
nicads.


That's not been my experience, Mike. In most cases, it has taken
considerably longer to charge NiMH batteries in chargers designed
exclusively for NiCad batteries. And, in some cases, there have been
problems with proper charger operation - ranging from chargers never
turning
off, resulting in overcharged batteries if not supervised, to some
"smart"
chargers refusing to charge the NiMH batteries at all.

In general (there are always exceptions), a person should use a
charger
designed for the batteries being charged. There are many chargers today,
internal and external, designed to accept both NiCad and NiMH batteries.
Older equipment usually doesn't offer this dual capability.

I've tried charging NiMH batteries in the Pro-43. The batteries never
reached a full charge, even after almost two full days of charging. At
that
point, I gave up and went back to standard NiCads.
